Natural Pools in João Pessoa: a complete guide
Seixas, Picãozinho, Areia Vermelha and Penha: how João Pessoa's natural pools work, best tide and what to expect from each one.

What João Pessoa's natural pools are
Natural pools are shallow areas of water formed by coral and sandstone reefs that emerge during low tide. At high tide, the sea covers the reefs and the pools cease to exist. At low tide, the reefs emerge or sit just below the surface, forming natural pools with warm, transparent and calm water. João Pessoa has four main natural pools, each with a different character: Seixas, Picãozinho, Areia Vermelha and Penha.
Seixas Natural Pools: the easternmost point of the Americas
Praia do Seixas is at the easternmost end of João Pessoa, at the same point as the Cabo Branco Lighthouse — the place that receives the first sun rays of the American continent every day. The Seixas natural pools are formed by an extensive line of reefs between 500 meters and 1 km from the beach. At low tide, the area is accessible and you can walk across the reefs, snorkel in the pools and see colorful fish and corals. Access is by boat or jangada from the beach. Seixas is the most sought-after tour in João Pessoa and depends entirely on low tide to work well.
Picãozinho: the natural pool inside João Pessoa's shoreline
Picãozinho is about 700 meters from Praia de Tambaú, accessible by boat in just a few minutes. Being inside the city shoreline, it's the closest and easiest natural pool to fit in a half-day itinerary. The water is shallow and calm, recommended for children and for those who prefer a more relaxed experience. At low tide, the reefs emerge and form a maze of pools with small fish and coral. It's a great starting point for those who haven't visited Paraíba's natural pools before.
Areia Vermelha: the island that appears and disappears with the tide
Areia Vermelha isn't technically a reef pool — it's a sandbar that's submerged at high tide and emerges as an island at low tide. It sits off the coast of Cabedelo, on João Pessoa's North Coast. Access is by catamaran from the Jacaré River. At low tide, the island has a natural pool around it formed by where the Paraíba River meets the Atlantic — the water turns greenish from the river sediment and has a mild temperature. It's one of the most visual and photogenic tours in the region.
Penha: natural pools on the South Coast
Praia da Penha is on João Pessoa's South Coast, farther from the center, with natural pools formed by reefs similar to Seixas. It's a less mass-tourism beach, which means fewer people and more tranquility. Access is via the South Coast and can be combined with other points on the same route.

How the tide determines which natural pool to visit and when
Each natural pool has its ideal tide window. Seixas and Picãozinho work best with low tide above [TO CONFIRM WITH MURILLO: ideal minimum coefficient]. Areia Vermelha depends on low tide for the island to emerge. The tide table changes every day — low tide can be in the morning one day and in the afternoon the next. The most practical way to plan is to check the table for your dates or talk to Murillo on WhatsApp: he checks the table and tells you which natural pool is best for your day and time.
Frequently Asked Questions
What's the difference between Seixas and Picãozinho?
Seixas is at the easternmost end of João Pessoa, near Cabo Branco Lighthouse, with pools between farther reefs offshore. Picãozinho is within the city shoreline, accessible by boat from Praia de Tambaú. Picãozinho tends to be calmer and shallower, recommended for families with children. Seixas has larger, more open pools. Murillo will tell you which to pick based on your profile and your day's tide conditions.
Do I need to know how to swim to visit the natural pools?
At low tide, the natural pools are usually shallow enough to stand in most areas. Life vests are available onboard. Even non-swimmers can safely enjoy most of the pools — especially Picãozinho and Seixas. Let Murillo know on WhatsApp if you have any limitation so he can recommend the best tour for your group.
How do I know if the tide will be good on my day?
The most direct way is to check the official Brazilian Navy tide table for João Pessoa and see if low tide falls in the morning or afternoon of your day. But the easiest way is to message Murillo on WhatsApp with your dates — he checks the table and lets you know if your day has a good tide and at what time.
